When struggling songwriter Dave Seville (Jason Lee) opens his home to a talented trio of chipmunks named Alvin, Simon and Theodore, they become overnight music sensations. But when a greedy record producer (David Cross) tries to exploit the "boys", Dave must use a little human ingenuity and a lot of 'munk mischief to get his furry family back before it's too late! Based on the characters of the same name created by Ross Bagdasarian, Sr., this animated comedy film stars Jason Lee, David Cross and Cameron Richardson with the voices of Justin Long, Matthew Gray Gubler & Jesse McCartney.
